Abstract
The invention relates to a connecting processing method for a containment pouring pile and a basement structure top plate in an inverse foundation pit. The method specifically comprises the steps that firstly, the containment pouring pile is constructed, and a top pressing ring beam is manufactured on the top; secondly, the top plate of a basement structure is constructed, an outer wall ring beam is arranged on an outer wall, a downward protruding groove is formed during pouring at the outer wall ring beam, and an outer wall water stopping steel plate is fixed to the protruding groove, wherein the protruding groove is arranged downwards by 10 cm, and the width of the protruding groove is 20 cm; and thirdly, the outer wall ring beam and the top pressing ring beam of the containment pile are connected through a concrete connecting beam. By means of the connecting processing method, damage, caused by pulling, of the outer wall ring beam and the top pressing beam of the containment pouring pile can be avoided, integrity of the outer wall water stopping steel plate is greatly improved, and it is avoided that a ring beam steel bar penetrates the outer wall water stopping steel plate, and leakage is caused; and the technique feasibility, work efficiency and the implementation effect of the connecting processing method are greatly higher than those of a traditional mode.
Description
Technical field
Inverse make to go along with sb. to guard him the connection processing method of bored concrete pile and basement structure top board in foundation ditch the present invention relates to a kind of.
Background technology
At present, in the area that environment is more complicated, Jing carries out foundation pit construction frequently with contrary sequence method, and knot is gone along with sb. to guard him in contrary sequence method
Structure typically selects diaphram wall, and as basement structure outer wall, this is gone along with sb. to guard him form waterproof mainly by ground wall self waterproofing, is connecing
Individually processed again at seam.And for small-scale pit or the base pit engineering for having compared with multi-obstacle avoidance in, ground wall is less suitable for, therefore adopts
With bored concrete pile as form of going along with sb. to guard him, but bored concrete pile cannot function as basement structure outer wall, and top board structure adopts reversed construction elder generation again
In base arrangement construction, now collar tie beam is poured and completed at exterior wall, and remaining external wall structure needs to be poured upwards after the completion of base plate
Build, at exterior wall collar tie beam construction joint is generated.Steel plate for sealing water, but the way are directly set at exterior wall collar tie beam at traditional construction seam
The drawbacks of be have more horizontal hoop at exterior wall collar tie beam, stirrup and steel plate for sealing water have more overlapping, and the overlapping is adopted substantially
With cut off or horizontal hoop on the mode lifted, but this way has one to the integrity of steel plate for sealing water and the effective depth of collar tie beam
Fixed infringement, it is undesirable in difficulty of construction and on implementation result.
The content of the invention
The present invention be to provide for it is a kind of it is inverse make to go along with sb. to guard him the connection processing method of bored concrete pile and basement structure top board in foundation ditch,
Waterstop joint point is processed at External Wall collar tie beam, and the method can avoid the inverse sealing mode of making in foundation ditch of tradition due to collar tie beam level hoop
Muscle causes steel plate for sealing water to cut off, low construction efficiency, the shortcoming of stagnant water effect difference.
For achieving the above object, the technical scheme is that：One kind is inverse to make to be gone along with sb. to guard him in foundation ditch bored concrete pile with basement knot
The connection processing method of structure top board, comprises the concrete steps that：
1）Bored concrete pile is gone along with sb. to guard him in construction, and top makes the collar tie beam that bears down on one；
2）Carry out basement structure top board construction, at exterior wall arrange exterior wall collar tie beam, arrange when pouring at exterior wall collar tie beam to
Under tongue, fixed outer wall steel plate for sealing water at tongue；
3）Exterior wall collar tie beam and being beared down on one for fender post be attached using concrete coupling beams between collar tie beam.
Reinforcing bar to arrange a Φ 12 in fixed outer wall steel plate for sealing water, the tongue is hung on exterior wall circle as reinforcing bar
At the cage bar of beam, reinforcing bar hook lower end is fixed with steel plate for sealing water using spot welding.
Downward length 10cm of the tongue, width 20cm；
The invention has the beneficial effects as follows：Using the present invention, exterior wall collar tie beam can be avoided and bored concrete pile capping beam is gone along with sb. to guard him due to receiving
Drawing is damaged, and has greatly reinforced the integrity of exterior wall steel plate for sealing water, it is to avoid is penetrated by ring beam reinforcing steel bar and is caused seepage, it is in skill
Traditional approach is all much stronger than on art feasibility, work efficiency, implementation result.
Description of the drawings
Fig. 1 is to go along with sb. to guard him bored concrete pile and basement structure top board connection diagram.
Specific embodiment
Below in conjunction with the accompanying drawings the invention will be further described with embodiment.
As shown in figure 1, it is a kind of against making to go along with sb. to guard him the connection processing method of bored concrete pile and basement structure top board in foundation ditch, specifically
Step is：
1）Bored concrete pile 1 is gone along with sb. to guard him in construction, and top makes the collar tie beam 2 that bears down on one；
2）Carry out basement structure top board 5 to construct, exterior wall collar tie beam 4 is set at exterior wall, arrange when pouring at exterior wall collar tie beam 4
Downward tongue 6, fixed outer wall steel plate for sealing water 7 at tongue 6；Downward length 10cm of tongue 6, width 20cm；
3）Exterior wall collar tie beam 4 and go along with sb. to guard him bearing down on one for bored concrete pile and be attached using concrete coupling beams 3 between collar tie beam 2.
Reinforcing bar to arrange a Φ 12 in fixed outer wall steel plate for sealing water 7, the tongue 6 is hung on outer as reinforcing bar hook 8
At the cage bar of wall collar tie beam 4, reinforcing bar is linked up with 8 lower ends and is fixed using spot welding with steel plate for sealing water 7.
The present invention at basement structure outer wall arrange exterior wall collar tie beam, exterior wall collar tie beam with go along with sb. to guard him bored concrete pile bear down on one collar tie beam adopt
Concrete connecting-beam is attached.To ensure exterior wall connection effect and stagnant water effect, it is vertical that downward exterior wall is set at exterior wall collar tie beam
Joint bar, additionally, mouth arranges downward tongue under exterior wall collar tie beam, steel plate for sealing water is hung at tongue, it is to avoid exterior wall ring beam reinforcing steel bar is worn
Thoroughly steel plate for sealing water, damages.
